You sound pretty experinced to me! ;-)

For a little coil, the pipe ground may be fine.  As long as it is a cold
water pipe and is not plastic anywhere before it goes underground, it is
probably fine.  We all like to have super good and elaborate grounds but
that is not always possible.  Perhaps you can run a wire down to ground out
a window?

With a bipolar coil, you should still hook the center to something but the
RF current will be far less in a bipolar coil.  Turn all the electronic
stuff off and pull phone lines, long wires, and antennas out of it that may
pick up RF power.  I would think two foot arcs and such would be safe but
there is always a chance you my kill something.  Such is the life of
coiling...  I have never really missed my answering machine... ;-)))

That's all the fun!!!
